Eugene Allen family-1870's-Worcester Co,

I have been successful in getting a birth certificate on my mother-Ella Alice Allen- She was borm 9/7/1873 in Brookfield, Ma.However birth certificate only gave name of father, Eugene Allen.I understand there were two brothers to mother-Thayer and Earl Allen, and two sisters-Grace and Annie Allen, but I can get no more information on any of the family.Does anybody have access to a 1880census that might list the family in Brookfield?
